What type of memory is ROM?

What type of memory is ROM?

Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.

What is a semiconductor memory?

Semiconductor memory is a type of semiconductor device tasked with storing data. There are two electronic data storage mediums that we can utilize, magnetic or optical. Has high storage capacity. Doesn’t use a laser to read/write data. Magnetic storage devices are; Hard disk , Floppy disk, Magnetic tape etc.

Is CD-ROM a semiconductor memory?

The correct answer is secondary memory. CD-ROM stands for Compact Disc-Read Only Memory. It is used for storage of Secondary memory or secondary storage. Semiconductor memory is a class of computer memory devices consisting of one or more integrated circuits.

What type of memory is RAM and ROM?

Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called as read write memory or the main memory or the primary memory. The programs and data that the CPU requires during execution of a program are stored in this memory.

What are the key properties of semiconductor memory?

What are the key properties of semiconductor memory? They exhibit two stable states, which can be represented by 0 or 1, they are capable of being written into to set the state, and they can be read to sense the state.

Is ROM magnetic storage?

As a result, most computer systems use magnetic storage for non-volatile storage of large amounts of data (typically in a form of a hard-disk drive) but a different type of storage for system memory, such as read-only memory (ROM), which is much smaller but can be accessed much faster.

What does CD-ROM mean?

compact disc read-only memory
CD-ROM, abbreviation of compact disc read-only memory, type of computer memory in the form of a compact disc that is read by optical means. A CD-ROM drive uses a low-power laser beam to read digitized (binary) data that has been encoded in the form of tiny pits on an optical disk.

How is a ROM used in semiconductor memory?

A ROM is a form of semiconductor memory technology used where the data is written once and then not changed. In view of this it is used where data needs to be stored permanently, even when the power is removed – many memory technologies lose the data once the power is removed.

What does read only memory ( ROM ) stand for?

ROM stands for read only memory, a solid-state semiconductor memory that can only read data stored in advance. Its characteristic is that once the data is stored, it can no longer be changed or deleted. It is usually used in computer or other electronic devices, and even if the power is turned off, the data will not disappear.

What kind of memory does a CD ROM have?

A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 textpages. Semiconductor memory is a type of semiconductor device tasked with storing data.

How is data stored in a semiconductor memory?

As a result, this type of semiconductor memory technology is widely used for storing programs and data that must survive when a computer or processor is powered down. For example the BIOS of a computer will be stored in ROM. As the name implies, data cannot be easily written to ROM.
